1. Power switch. Switches the unit on and off. Make sure to switch the unit off when not in use.
2. AC input. Connect the supplied AC/AC power supply unit here. DO NOT use any other power supplies than the supplied one or a
genuine spare part.
3. Headphones output. A ¼” TRS connector to connect a headphone. Turn the CUE level (15) down before plugging in
any headphones.
4. Main stereo output. This is an unbalanced output, with its level adjustable by the Master volume control (19).
5. Record output. This is an unbalanced stereo output carrying the same signal as the main output (4), but not influenced by the main
volume control (19). This is normally used for recording the output to an external tape, CD or memory device.
6. Line inputs. These RCA connectors provide inputs for line-level signals to the assigned channels. The input sensitivity can be
switched to PHONO (with RIAA equalization) by means of the input switches (8).
7. Microphone input. This is an unbalanced TRS connector without phantom power provision, hence only suitable for
dynamic microphones.
8. PHONO/LINE selector switches for line inputs. These switches change the sensitivity of the line inputs between PHONO (RIAA
equalized) and LINE level. In released status, the input sensitivity is set to LINE and the indicator LED inside the switch is off, in
pressed status, the input sensitivity is set to PHONO and the indicator LED inside the switch is lit.
9. Gain control of input channels. Allows adjustment of the input sensitivity to compensate for different source volumes. To facilitate
proper setting of input gain levels, the headphone bus (CUE) and thus the input level can be routed to the LED meter by the meter
source switch (21).
10. Channel Equalizer. Allows the adjustment of the tonal balance for each of the stereo inputs in three music-specific frequency
bands with an adjustment range of -26/+12dB.
11. CUE switch for stereo channels. Assigns the respective channel to the headphone bus for pre-fader-listening (CUE). A LED
indicates the pressed position.
12. Channel fader for input channels. A high-grade 45mm fader determines the volume of the respective channel.
13. Crossfader. A high-grade 45mm fader determines the mix ratio between the stereo signals of channel 1 and channel 3.
14. Microphone tone control. Allows tonal adjustment in two voice-specific frequency bands with an adjustment range of ±12dB.
15. Microphone level control. Sets the microphone level.
16. Talkover switch. This momentary switch allows to reduce the music level by 20dB during the switch is pressed, when an
announcement is made through the microphone.
17. CUE Mix control. This control determines the mix ratio between the Main signal and the CUE signal on the headphones. If you
wish to only hear the CUE signal (which contains all channel signals of those channels where the CUE switch (11) is pressed), turn
the control to fully left position, if you wish to only hear the Main Output signal, then turn to the fully right position. Any position in
between delivers a mix of the two signals.
18. CUE volume. Determines the signal volume at the headphone output (3). Always set this control to minimum before putting on
headphones, as sudden high-volume impact may damage your ears. See further health advice below.
19. Main output level control. Determines the main output level present at output (4).
20. Level meter. Depending on the setting of switch (21), this meter will either display the level on the Main output (4) or the level of
the CUE signal (which contains all channel signals of those channel where the CUE switch (11) is pressed).
21. Meter source switch. Decides whether the master output signal (4) is displayed in stereo on the level meter (20) or whether the
level of the CUE signal (which contains all channel signals of those channels where the CUE switch (11) is pressed) is displayed
on the level meter (20). In released position, the master signal is displayed, in pressed position, the CUE signals is displayed and
the indicator LED inside the switch it lit.
For versions with AUX input:
22. AUX input. This is a 3.5mm Mini TRS socket, designed to accept line level signals as for example from mobile media players or
mobile CD players. This input is a switchable input option for stereo input channel 2.
22. SKIP FWD key. Press this key to jump to the next track stored on the MP3 memory source.
23. Play/Pause key. Start the replay or pause the replay of the currently chosen MP3 track.
24. SKIP BWD key. Press this key to jump to the previous track stored on the MP3 memory source.
25. USB (type A, female) socket to allow connection of a flash memory device (USB stick).

CONNECTIONS
For connecting this unit to AC mains, please note that before plugging the AC/AC adaptor in the wall outlet, check whether the AC mains
voltage and frequency is the same as this products’ AC/AC adaptor is specified for (see label on AC/AC adaptor). Whenever the specified
voltage or the AC plug of the AC/AC adaptor should not match the local conditions, do NOT plug the AC cord into the wall outlet and
contact you dealer immediately..
For making audio signal connections, always remember that good and reliable connections are a basic requirement for good sound and
reliable operation. Bad soldering of cables can result in intermittent audio signals or temporarily lost ground connections, hence always
use good cables. In case of doubt about making proper connections, please see check the standard pin assignments required for proper
operation in the appendix of this manual.
POWERING UP
Following a proper power-up sequence protects your equipment – specifically speakers – and your ears. Follow the below procedure:
1. Turn down all output volume controls of any equipment in your audio system.
2. Switch on your audio sources first (Turntables, CD Players, PC’s with soundcards, Tapedecks, etc.)
3. Switch on the audio mixer
4. Switch on any audio processor between the mixer and the amplifier(s) [if any].
5. Switch on the amplifier(s).
6. Turn up the audio level on your sources if such controls are provided.
7. Set the audio output of your mixer to a low level.
8. Set the audio output of any audio processor between the mixer and the amplifier(s) to a medium level [if any such processors].
9. Turn up the volume controls of your amplifier(s) slowly.
10. Make adjustments to all volume settings as needed.
For switching off, follow the inverse sequence – always switch off your amplifier(s) first, then any processors between mixer and
amplifier(s), then the mixer, then the sources.
The MP3 player option can not be retrofitted. If your product is delivered with an AUX input, it can not be modified to add the
MP3 player. For proper replay, please note that:
1. The maximum size of the source flash memory can not be bigger than 32MB; for some flash memory brands, the maximum size
may be smaller (8/16GB).
2. The maximum supply current to the USB bus is 50mA. This is NOT suitable to connect a hard disc or similar devices – only flash
memory is permitted.
3. certain brands and types of flash memory may not be compatible with this player. Preferably, well known branded USB sticks
shall be used. Avoid to use USB adaptors for SD cards, micro-SD cards etc.
4. You must apply proper alphanumerical file names to your MP3 files if you want them to be played in a certain sequence.
5. This MP3 player does not recognize folders. All MP3 files must be stored in the root directory of the memory.
General notes for the MP3 version:
OPERATION
Apart from using good equipment, good sound comes from using it correctly. Level setting mistakes are one of the common reasons
why even good equipment may not perform as desired. For setting levels, please be reminded that two guidelines need to be followed:
1. Avoid distortion by leaving some headroom. Never overrun any audio-equipment’s inputs. Level meters and displays allow you to
make sure that signals do not enter critical levels.
2. Avoid unnecessary amplification by using as little attenuation as possible. For example, if you turn down the input gain of a mixer
to minimum, and then increase the main output of the mixer to maximum to drive your amplifier properly, you will create unnecessary
noise, as you first dispose of some already existing signal level, and then later apply amplification (tainted with noise) to make it up.
Obviously, these two requirements are marking a levelling window that the operator must match to achieve a good sound with as little
distortion and noise as possible.
DANGER: Excessive volume levels on headphones or other sound systems may
cause hearing damage. Always turn the volume control to minimum when you
switch the unit on, and do not exceed healthy listening levels.

MAINTENANCE AND WARRANTY
While we have chosen the best components to make this product as rugged and reliable as possible, some parts in audio products
(potentiometers, faders, switches) are subject to wear which is a matter of operation cycles, and not of time. While providing a full time-
based warranty according to the country’s of purchase requirements on the function of the electronic circuitry, we hence have to limit
the warranty on such electro-mechanical parts to 90 days from the date of purchase.
In many cases, malfunction of electro-mechanical parts occurs due to dust contamination, which may require cleaning of such parts.
As the inside of such parts is not accessible, a common practice is to use cleaning fluids in the shape of sprays. Please be reminded
that many of such fluids contain chemicals which may wash away the dust but at the same time corrode or damage contact surface and
may cause cosmetic damage to other parts. We hence explicitly exclude any claims for exchange of damaged part due to mechanical or
chemical impact.
Without liability, we recommend CaiLube MCL fader cleaner and lubricant available from CAIG Laboratories if the need of cleaning for
electro-mechanical parts occurs.
Further to that, this unit does not need regular maintenance.
